Editorial data comparison
Mitsubishi Heavy ZS-W vs ZSX-W
This comparison uses the complete 20 W combinations, giving equal nominal cooling capacities side by side. Findings for these units are not a blanket assessment of every ZS or ZSX generation or size.
Editorial update: · KLIMAFAKTUR
The comparison enquiry treats the units as alternatives. They are not prefilled as items to order together.
Selection at a glance
For this combination ZSX-W has higher SEER/SCOP values but a wider indoor unit. Both have the same documented minimum indoor sound pressure; fan settings and the full acoustic range still matter in use.

Scope of the figures
Indoor: Ultra Low to High; outdoor: nominal. Cooling mode.
Energy efficiency is determined by the energy label of the complete supplied model. We provide the relevant energy documents with your quotation.
Balance efficiency and casing size
Seasonal efficiency can matter for regular heating or cooling. At a fixed installation location, actual dimensions and required clearances also govern the choice. The higher efficiency figure alone does not identify the right unit.
Keep W and W2 references separate
Other ZS-W sizes have documented outdoor-suffix differences. That is why this page uses only the supported 20 pair. For other sizes, request the exact combination instead of transferring these figures to 25 or 35 sets.
Frequently asked questions
- Is the series name sufficient for ordering?
- Ordering requires both full model numbers. “ZS” or “ZSX” identifies the series, not the capacity, version, outdoor unit and delivery contents of the actual line item.
Manufacturer documentation
The manufacturer documents provide further information about features, installation and operation. We help you choose the right version and accessories.
